Wireless Device Authentication Using Digital Certificates

1. A method, with a wireless device, for providing authentication information to a network, the method comprising: determining that at least one authentication context resides in memory, wherein the authentication context includes authentication credentials for authenticating the wireless device; analyzing the at least one authentication context to determine if at least one realm identifier associated with a home service provider is included in the at least one authentication context and wherein the realm identifier identifies a home realm of the wireless device and includes a unique wireless device identifier and an identifier associated with the home service provider of the wireless device; prompting, in response to determining that at least one realm identifier fails to be included in the at least one authentication context, a user to update the at least one authentication context with at least one realm identifier associated with a home service provider; receiving from a user at least one of a user selection of at least one realm identifier associated with a home service provider, and user data entry identifying at least one realm identifier associated with a home service provider; and updating, in response to the receiving, the at least one authentication context with the at least one realm identifier received from the user.

2. The method of claim 1 , further comprising: detecting a wireless communication network; and sending a registration request including the at least one authentication context comprising the at least one realm identifier, wherein the at least one authentication context is used as an authentication credential by the wireless communication network.

3. The method of claim 1 , wherein the authentication context comprises an immutable digital certificate and private key.

4. The method of claim 3 , wherein the immutable digital certificate is a X.509 digital certificate.

5. The method of claim 1 , wherein the receiving further comprises: receiving the at least one realm identifier associated with a home service provider from the user via a graphical user interface.

6. The method of claim 1 , wherein the receiving further comprises: receiving an over-the-air update comprising the at least one realm identifier associated with a home service provider.

7. The method of claim 1 , wherein the updating further comprises: updating the authentication context with a plurality of home service provider realm identifiers.

8. A wireless device comprising: a memory; a processor; and a service manager communicatively coupled to the memory and the processor, wherein the service manager is adapted to: determine that at least one authentication context resides in memory, wherein the authentication context includes authentication credentials for authenticating the wireless device; analyze the at least one authentication context to determine if at least one realm identifier associated with a home service provider is included in the at least one authentication context, wherein the at least one realm identifier includes a unique wireless device identifier and an identifier associated with the home service provider realm of the wireless device; prompt, in response to determining that at least one realm identifier fails to be included in the at least one authentication context, a user to update the at least one authentication context with at least realm identifier associated with a home service provider and wherein the realm identifier identifies a home realm of the wireless device; receive at least one realm identifier from a user; and update, in response to the at least one realm identifier being received, the at least one authentication context with the at least realm identifier received from the user.

9. The wireless device of claim 8 , wherein the service manager is further adapted to: detect a wireless communication network; and send a registration request including the at least one authentication context comprising the at least one realm identifier, wherein the at least one authentication context is used as an authentication credential by the wireless communication network.

10. The wireless device of claim 8 , wherein the authentication context comprises a digital certificate.

11. The wireless device of claim 10 , wherein the digital certificate is a X.509 digital certificate.

12. The wireless device of claim 8 , wherein the service manager is further adapted to receive by: receiving the at least one realm identifier associated with a home service provider from the user via a graphical user interface; and receiving an over-the-air update comprising the at least one realm identifier associated with a home service provider.

13. The wireless device of claim 8 , wherein the service manager is further adapted to update by: updating the authentication context with a plurality of home service provider realm identifiers.
